What we store

We store account details, worksheet settings and content, subscription status, and product events needed to run and improve the service. Guest worksheets expire automatically. Please do not enter student names or sensitive student information.

Generation providers

When language generation is needed, worksheet context and teacher-provided content may be sent to OpenRouter and the selected model provider. Deterministic mathematics is generated locally and is not sent to an AI provider.

Email and payments

Brevo delivers transactional email. Stripe processes subscription payments. We do not store card numbers.

Your choices

You can delete worksheets and request account deletion. Shared worksheets are private until you create a share link.
